There is an error injection framework we can use nowadays, or maybe you can
put this in tools/powerpc ?

Ben, we don't have error injection framework yet. I have one source file "eeh-debug.c"
which exports P7IOC registers through procfs. In order to force EEH errors (frozen PE
or fenced PHB), we need change the specific bits of corresponding HW registers through
the procfs entries (e.g. /proc/IODA/PHBx/REG).

I mean Linux has an error injection framework :-) We could hook up something into it.

Cheers,
Ben.
